ALBERT M. COX, 0]? MATTIE, SOUTH CAROLINA.

GROUND CUTTER AND. PULVEBIZER.

To all whom it may concern: I

Be it known that I, ALBERT M. Cox, a citizen of the United States, residing at Mattie, in the county of Horry, State of South Carolina, have invented certain new.

and useful Improvements in Ground Cutd I do hereby deters and Pulverizersg an a full, clear, and

clare thefollowing to be exact description of will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to farm implements and more particularly to an improved ground cutter and soil pulverizer.

The essential purpose of the invention is involved in the provision of an improved implement or machine of this character to be drawn by horses or other draft animals and intended for the breaking up of the ground, 1 leared ground,

especially rough and unc so that the ground will be cut transversely and longitudinally at one advancement of the machine across a field.

Another object resides in the provision of cutting devices which may be readily assembled or disassembled and which are of to conduce to durability to economy in manufacsuch simplicity as and strength and ture.

WVith the above and other objects in view the invention consists of certain other combinations and arrangements of parts, as will be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my improved ground cutter and pulverizer with the parts in a raised or inoperative position. Fig. 2 is a longitudinal sectional view taken inwardly of one side beam with the implement part in an operative position. Fig. 3 is a top plan view. Fig. 4 is a cross sectional view taken on the line 4-4 of Fig. 3. Fig. 5 is a central longitudinal sectional view of the machine. Fig. 6 is an enlarged detail view showing the manner of attaching one of the cutting blades.

As illustrated, my improved ground cutter and pulverizer embodies a rectangular supporting frame 10, the rear end of which forms the rear axle 11 having ground wheels 12 mounted on its ends while the forward end of the mach'ne has a bearing projection 13 pivoted to the front axle 14: by a king bolt 15 and ground wheels 16 are mounted on the ends of the front axle to Specification of ltetters Patent. Application filed July26, 1912. Serial No. 711,670.

the invention, such as overlapped relation comprises side provided for Patented July 14, 1914:.

provide a wheeled frame for supporting the working parts; A'tongue 17 is connecte to the front axle by the usual hounds 18 which secure the same rigid therewith for turning the front axle by suitable draft animals so that the front wheels can turn at comparatively sharp angles to avoid stumps or other obstructions.

Thecorners of the Supporting frame are mortlsed as shown at 19 and secured. in

wedge pins 20 so as to securely lock and hold the parts of the frame together. A seat standard 21 is mounted on the front end member of the frame and supports a seat 22 for the driver and the central portion of the frame is connected by a cross brace 23 which considerably reinforces the frame structure.

A cutting device for cutting the soil in the direction of travel of the machine, is arranged at the forward end thereof and arms 24 mounted at their forward ends for pivotal movement upon the reduced extremities of a transverse pivot 25, such extremities beingengaged in transversely alined apertures in the side beams of the'frame. The arms 23 are connected intermediate their ends by the cross brace 26 andat their rear ends by a cutter bar 27 which are secured rigidly to the arms, while the cutter bar is provided with spaced recesses 28 in its bottom face providing an intermediate and end enlargement having recesses 29 communicating with their forward and bottom faces. These recesses are provided with enlarged circular upper portions 30 and are adapted to receive similarly shaped heads 31 of rearwardly extending cutting knives or blades 32 adapted to cut the soil.

The pivoted supplemental frame thus the cutters 32 which are removably attached as described, is provided with a platform 33 having a rear vertical retaining pOrtion 34: for the retention of suitable weights mounted on the platform for embedding the knives in the ground, especially when the latter is rough. An operating lever 35 is centrally mounted in the upper forked extremity of a standard 36 centrally mounted on the cross brace 23 and has its forward extremity connected by a flexible member 37 to the cutter bar while the rear extremity of the lever extends slightly beyond the rear end of the frame through the medium of for hOlding the lever for manipulation to raise and lower the cutter blades. to the lever A depending link 38 issecured rearwardly of the standard and 1 engages a pin 39 carried by the standard and. the blades out ground, while said link in a lowered position of contact with the ma be 'swun to a disengaged position for lowering the blades,

A slmllarl y constructed frame 40 is pivoted rearwardly of the cross brace 23 except that the rear ends of the arms, which in both inst their under edges to ances are curved on prevent them from projecting into the-earth, rotatably support a pulverizing wheel having removable 41 embodying a cylinder end plates 42 closing the extremities of recesses 43 extended longi tudinally of opposite ends of the cylinder 1; drum, spaced apart centrally and arranged in staggered relation for removably securing cutting blades blades extend radially fr at a slight angle and transversely the 44 therein. These om the cylinder and to the direction of rotation thereof to' cut and pulverize the soil behind direction of operation of the cutting blades.

1 A lever 45 is pivotally mounted upon a standard 46 carried centrally of the rear axle and beneath the lever and is connected at its forward extremity by a flexible member 47 to the cross brace of the supplemental frame and provided with a simi- 3 lar link and pin for holding the lever in por sition with the blades in or out of contact with-the ground as desired. 1

From the foregoing neetion wlth the accomp Copies 01. thia'patent may be obtained for five cents each, by Washington, Ill-O.

description in conanymg drawings, it

may be made to supplementalcesses; being so disposed that 1. In a pul'verizing machine, the combination of implement holding members having recesses provided with interior circular enllargements and cutting implements having.

similarly shaped necks and head portions removably engaged in sald recesses.

J In a ground cutter and pulverizer,.an

implement holding member having recesses out in 1ts face ad acent'the ground, each of said recesses also opening upon an adjacent side of the member, each of said recesses bemg provlded with lnterlor circular enlargements and cutting implements having simi-- larly shaped neck and head portions removably engaged in said recesses, and said-rewhen the machine is assembled and in I operatlon, the I heads of the cutting-implements are securely held in said enlargements.

In testimony whereof, I affix my signature, in presence of two witnesses.
